40, the space at the rear of the incinerator chamber, between the rear wall of the incinerator chamber and the rear wall of the cas ing: and all, the space at the front of the incinerator chamber betweenthe front wall of that they maybe separated from each other incinerator chamber is filled up and removed from the casing through the door-openings, and without the use of tools. In my present practice in constructing the incinerators for domestic use for the incineration of garbage or other waste, the device is intended as a substitute for the usual garbage or waste can into which garbage the burners unlighted, the feed-door being opened as occasion requires for putting the garbage into the incinerator. No'attention need be given to the drying of the garbage being charged into the incinerator as the incinerator will drive off all the moisture before consuming the garbage, but it will of course be obvious that the greater the quantity of water carried by the garbage the greater will be the consum tion of gas employed in its incineration. t is, of course, to be understood that, when the device is not in use as an incinerator, the dumping grates will be in closed position, as indicated in full lines in Fig. 6. As the garbage is from time to time charged into the incinerator, if the garbage is in specially wet condition, water will drain from it into .the ash-pan. The keeping of the register closed before the incinerator is put into operation, is important in preventing the escape of odors, if chimney draft is weak. With strong chimney draft the register may be left open to permit a drying circulation.

The incinerator having been charged to theproper height, it is in order to proceed with the incinerating operation, and before this is done it isdesirable that the top of the mass be poked into reasonably level condition. The register is now to be slid open;

the hood, and heated gases pass up through the mass; the first'effect of the heat is to evaporate the moisture from the garbage,

the vapor passing out through the chimney outlet; 1n the early stages of the incineration some of the vapor may be condensed and drop down into the annular water-pan; the lower portion of the mass, being closer to the heat, will finally go itself into combustion; when this combustion has proceeded to a proper degree it may be depended upon for the Completion of the incinerating process, and the gas burner may be shut off; the incineration proceeds till the mass is reduced to ash; the ash drops down through the grate and into the ash-pan and forms good fertilizing material; if the mass shows a tendency toward arching, the use of a poker will be in order; the 'incinerating process will be expedited by opening the ash-door somewhat but this door and its register should always be closed when incineration is not goingon; when the mass is completely reduced then the dumping handle is operated and the dumping grates swung sidewise, as indicated in Fig.6; remaining' ashes and incombustible matters then fall to the ash-pit; the'grates are to be closed for new charges; the ash-pan is then to be removed and emptied.

lVhile it is preferable that the beginning of the incinerating process should be delayed till the incinerator chamber has been fullv charged, the burner may belighted and the charge incinerated, no matter what may be the quantity contained in the incinerator so long as it is worth while.

The dropping of liquid from the charges results in a deposit of water in the ashpan, and a condensation of vapors in the chimney connection above the incinerator results in the deposit of wat'erin the annular water-pan. However, when the charge has been fully incinerated it will be found that the heat of the lower portion of the incinerator chamber has evaporated thewater from the ash-pan, the vapor therefrom passing up the passages going to the chimney, while the waste heat from the top of the'incinerator chamber evaporatesthe .water from the "annular waterpan, this water-pan and the ash-pan bemg generally found dry at the end of the in cinerating operation.

Generally the garbage will arch .over the fiues formed between the vertical ribs of the fixed grates and dumping grates so as to permit upward passage of the heated products from the burner. But mushy portions of the. mass may, instead of arching across these fines, go into and fill up the fiues. Such mushy matters present themselves'at the ports in the grates and become subjected to heat rising from the base of the apparatus through the flues 12 at the sides of the incinerator, this heat drying and incinerating the material occupying the ports.

The prong on the register prevents the supply-cock being opened while the register 'heat, and a gas-burner disposed across he and form vertical flues between the material and--the walls for the upward passage of chamber parallel with theiribbed chamberwalls and having gas ajutages adapted to.

deliver flames to said flues, combined substantially' as set forth.
